To aZ whom it may concern.- 1

Be it known that I, MELVIN DELos LETTEER,

a citizen of the United States, residing at Dela-` van, in the county ofValworth and State of Wisconsin,- have invented a new and usefulCombinationffool, of which the following is a specification.

This invention relates to combin ation-tools; and the object in view isto vprovide a vhand implement embodying a pipe and nut wrench, a pair ofnippers, a screwdriver, a claw, and a rule, '&e.

The principal aim of the'in vention is to provide a wrench having anoperating-lever, and to employ in connection withthe sliding jaw andoperating-lever'an extensible connection or link interposed between theoperating-lever and the shanlrof the wrench, the-said extensibleconnection providing for a fine and accurate adjustment ofthewrench-jaws,such adjustment being independent of the vmovementimparted to the sliding jaw by the 0peratinglever.` f

Other objects and advantages of the invenv tion will appearin the courseof the ensuing description.

The invention consists in certain novel'features anddetails ofconstruction and arrangement of parts, as hereinafterfully described,illustrated in the drawings, and nally pointed out in the claims heretoappended.

In the accompanying drawings, Figure 1 is a perspective view of acombination-tool constructed in accordance with the present invention.Fig. i? is a longitudinal section through the saine. Fig. 3 is a detailperspective view of' a portionof the main shank of 'the tool, showingthe adjustable sleeve and the retaining-dog carried thereby andengagin@r the shank. j -v Similar numerals of reference designatecorresponding parts in the'several figures of the drawings. Referring tothe drawings, 1 designates the main stock or shank of the tool, which isproforming a screw-driver 2, and providedatits ,Other end with aright-angular extension forming a fixed wrench-jaw 3. Opposite the jaw 3is a cutting-jaw 4, forming one member of The slidingaw '5 isprovidedupon one sideof theV stogg with a longitudinal recess, and inthis rec ss is'mounted a sliding nipperfjaw G, adapted to meet at itscutting edge with the corresponding edge of the stationary ni p per-`jaw4. The jaw G is provided with alongitudinal slot 7, and a screw 8 passesthrough Both the jaw 5 'and said slot and also'through the-sliding jaw,l

said screw holding the jaw in`plaee,b`ut per- Apasses through the rearend of the sliding jaw 'and bears against the corresponding end of `thejaw 6, thus providing for the adjustment of said jaw when the samebecomes Worn at its cutting edge.

The stock or shank 1 is provided upon one side with a plurality oi'teeth 10, and a sleeve 11 surrounds the stop and' is mounted to slidethereon. vPivot-ally connected to said sleeve Vis a retaining-dog 12,adapted to hold lthe sleeve at any desired poi\nt on the stock.v This'dog is so arranged that it'may be swung into and out of engagement withthe teeth 10, and in order to facilitate this the dog is 'provided 'withan arm or extension 13,7whieh partially embraces the stock 1 and hassufiicient resilimitting alongitudinal movement of said jaw for thepurpose of adjustment.. A screw .fr

vo l

ency to enable the extremity thereof-to clasp around the stock with aspring-pressure, thus holding the dog in engagement with the teeth 10.1Thesleeve 11 maythus be disengaged and moved to any point on the stockand there held, or, if desired, lthe sleeve may be l entirely removedfrom the stock.v l,

14 designates the operating-leverywhich is connected at one end to thesliding -jaw 5 by a knucklejoint15. Betweenthis lever and the .sleeve l1is arranged an eXtensi-bleconn'ection,which consists., essentially, oftwo threada ed rods or'seetions 16, respectively connected tothe lever14 and sleevejll l'byalmuclrlejoint, as` indicated' at 17 and 1h.-v Theadjafv 'e'ent ends of these .sectionsare provided, .respectively, withright. and Ilefthand threads,

. nuts or pipes 'of widely-varying sizes.

the eXtensible connection.

threads, to correspond with the sections 1G of By adjusting theturnbuckle it 'will be seen that the distance Vbetween the sliding jawand sleeve may be readily and accurately adjusted. The extremity of thelever 14 is provided -with a V- shaped notch` 20, adapting said lever tobe used as a claw.

y InV operation the sliding jaw may be advanced toward the iixed jaw byvibrating -tlie lever 14C toward the stock or shank 1, the inwardmovement of the lever being limited by the claw end of said lever comingin contact with -the stock. It is desirable for many rea-g sons toprovide for an accurate adjustment of the distance .between theWrench-jaws, for instance, to enable the wrench to t any particular nutexactly or to enable the jaws to be used as calipers. At the saine timethe sleeve 11,with its dog 12, provides torl a greater amount o fadjustment for accommodating The several features and adjustmentshereinabove described cont'ribute to form a very useful and convenientcombination-tool, and it will be noted that the several parts of thetool are `soeonstructed and arranged as to afford the greatest possiblestrength. .When the' operating-lever is closed, the joints 15, 17, and18 are brought into longitudinal alinementt so that the tendency of thejaws of the wrench to move apart is overcome, and in addition to thisthe greatest power is brought to bear upon the jaws as the operating-lever approaches the stock of the tool.

It will be understood that the combinationtool is susceptible of variouschanges in the form, proportion, and minor details of construction,Which in ay accordingly be restored sleeve and pivotally Aadapted towithout departing from the lspirit or sacricing any of the advantages ofthis invention. Having thus described the invention, what is claimed asnew'iswith a fixed jaw, of a sliding jaw, an operating-lever havingpivotal connection with the sliding jaw, a sleeve on said stock, and aconnection interposed between said lever and connected to, said lever,said connectionbe'ing made extensible in length whereby the distance verand sleeve may be Varied, substantially as described.

, 2, The combination with the stock provided with a fixed jaw, of asliding jaw, an operating-lever having pivotal connection with thesliding jaw, and an extensible connection interposed between said leverand the stock 'and pivot-ally connected to the lever, intermediate theends of the latter, said connection consisting of inversely-threadedsections and a connecting-turnbuckle, all arranged substantially and forthe purpose described. 1-3. IIn a wrench havingl a fixed and slidingjaw, the combination with the sliding' jaw, of an operating-lever, asleeve embracing the stock and adapted to slide longitudinally thereon,a dog carried by said sleeve and to be moved into and out ofengagebetween the lement with teeth on thestock, and a connec.
